TIE-PLATE.

Application filed October 19, 1927.v Serial Nb. 227,229. r

The present invention relates to improvements in tie plates, and has for its primary object to provide a structure for disposition beneath the base of the rail, and for rest on the cross tie, the tie plate being provided with spike receiving openings and a transverse shoulder for engagement with one edge of the base of the rail, so that when the spikes are driven home into the tie, the rail will be properly secured on the tie plate, and lost motion as well as lateral play will be prevented.

Another important object of the invention is to provide an improved spike structure for association with the tie plate whereby to afford a wedging action of the rail against an upstanding shoulder formed on the tie plate when the spike is driven home.

A further object is to provide a tie plate which is simple in construction, inexpensive, strong and durable and further well adapted to the purposes for which it is designed.

Other objects and advantages of the in vention will become apparent from the fol- 2 lowing description when taken in connection with the accompanying drawing.

In the accompanying drawing forming part of this application and in which like numerals indicate corresponding parts:

Figure l is a vertical sectional view through a rail showing the manner in which the same is anchored on my improved tie plate, the wedging spike being also shown in its anchored position.

Figure 2 is a top plan view of the tie plate, and

Figure 3 is a detail perspective view of the locking spike.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a substantially rectangular shaped tie plate, the same being constructed of steel or any other desirable metal. A transversely extending shoulder 2 is formed on the upper face of this plate adjacent the outer end thereof, and as is clearly shown in Fig ure 1, the upper face of the tie plate is beveled and inclines gradually from the shoulder 2 to the inner end of the plateso that the rail A will be disposed slightly at an incline, as is clearly shown in Figure 1, when the base B of said rail rests on the tie plate. I 1 The outer end portion of the tie plate is formed with the spaced openings 3 and these openings are preferably formed in the. plate I so as to extend through the shoulders whereby the inner ends of the openings will be substantially flush with the base engaging are driven through the openings 3 into the.

tie C on whichthe tie plate 1 rests, and the heads of these bolts are adapted to engage the upper face of the outer edge portion of the base B of the rail in the manner as shown in Figure 1.

The tie plate is formed with an additional pair of elongated slots 5 adjacent its inner end and these slots are so arranged as to cause the inner end portions thereof to be disposed beneath the inner edge portion of the base B of the rail, when the base of the rail rests onthe tie plate.

A. spike such as is shown at 6 with reference more particularly to Figure 3 is adapt-- ed to be driven through each of these slots 5 andthis spike is provided with the base engaging head 7 at its upper end, the inner face or edge portion of the spike directly below the head being straight or parallel with the outer edge of the spike and this straight portion is designated by'the numeral 8. Di-

rectly below this straight portion 8 the inner edge of the spike is inclined as at 9 whereby to afford a wedging action when the spike is driven downwardly into the tie G, and when said spike 6 is driven home, the outer edge portion of the spike will engage the outermost ends of the respective slot 5 while the straight inner edge portion 8 will engage the inner edge portion of the base B. In this manner, the rail will be properly secured on the tie plate, with no lost motion or lateral play, the spikes 6 having greater holding power than the spikes 4, whereby the spikes 6' driven in the slots 5 would have to yield under the tie plate and under the load of the t-raflic. The spikes 4 cannot push out or back until the spikes 6 are kinked under the tie plate.

Furthermore the tie plate will be secured in position on the cross tie beneath the rail in such a manner as to prevent any possibility of the same rattling.

l Vhile I have shown the preferred embodiment of my invention it is to be understood that minor changes in the size, shape, and arrangement of parts may be resorted to without departing from the spirit of the in vention and e 0 en the a claim Havingthii d sc i i the iii feii oi, What I claim as new and desire to secure by Let ters Patent is In combination with a rail and across tie, a tie plate for disposition between the of the rail and the cross tie, a shoulder formed on the upper face of-"the tie plate has enga einent with the outer edge of the base ofthejrail, the upper face ofthe tie phite being" gradually i rielin edkfiom said shoulder to the inner end'of the plate I tie plate proi idedflvith spike receiving openings a'djacent'the outer end 'thereofg the innejr sides oftlie openings lying fiushliviththe basel e n gaging face of the shoulder, said tie pl ate beingprovided, with 'add'itiol ial 1 slots in the of-the. slots extending under the inner edge inner edge of theshailk directly below the heed heirigstraight, the portionofitlne-shank 'belowthe upper straight portion on the inneredge being gradually inclined toward the pointed lower end.
